Participants

Reaction Steps

30% Aqueous hydrogen peroxide (0.0618 mL, 0.6 mmol) was added to a solution of (E)-[4-[3-[4-(methylsulfanyl)phenyl]-3-[4-[3-(pyrazol-1-yl)propynyl]phenyl]allyloxy]-2-methylphenoxy]acetic acid (262 mg, 0.5 mmol; example 48) in glacial acetic acid (7 mL) at 5° C. under stirring. The mixture was left to stand over night at ambient temperature, diluted with water (40 mL) and extracted with ethyl acetate (2×20 mL). The combined extracts were alkalized with 15% aqueous solution of ammonium hydroxide; the solution was washed with water (10 mL) and brine (10 mL), dried with anhydrous magnesium sulphate and evaporated in vacuo. The residue was triturated with hexanes (3×15 mL) to yield the title compound as pale solid.
